Lecture #20 and #21 Wed May 13th and Fri May 15th

The three laws of Thermodynamics were covered and entropy and spontaneous reactions were introduced. We talked about the entropy of the universe and the entropy of a system.

Gibbs Free Energy was introduced and we discussed the relationship between free energy, entropy, and enthalpy. I touched on Experiment #32 (which we will not perform in this class) and how free energy is related to the equilibrium constant, k. This value can be experimentally determined via an acid/base titration.

Lastly, the chelate effect was analyzed as the magnitude of the formation constant can be analyzed by looking into the entropy of the reaction occurring.
